  • Added the "transparency" option to specify whether to convert transparency to opacity when outputting to PDF.

Conversion from Word

  • Added support for line number output.
  • Added the "-docnonlinenumber" parameter to suppress line number output.
  • Added the "conditional-2nd-pass" option to control docpagenumbercorrection.

Conversion from Excel (XLSX)

  • Enhanced support for form controls.
  • Added support for external hyperlinks.

Conversion from MS-Office (OOX)

  • Added support for outputting shapes and text with 3-D effects. Some 3-D format and 3-D rotation settings are not supported.

Other Conversions

  • Improved processing to prioritize BOM detection when converting text that contains a BOM.
  • Added the "preferred-encoding" option to specify the encoding to be prioritized when converting text.

Others

  • Changed the .NET interface from .NET 8 to .NET 10.
  • Added support for BMP image format output.
  • Added support for EMF+ (Enhanced Metafile Format Plus) rendering.
  • Changed the behavior of the "watermark-opacity" option and the "-wmarkopacity" parameter, which specify the opacity of watermarks, as follows:
    Old: The value range is 0.0 to 1.0, where 1.0 represents full opacity. Specifying 0.0 is invalid and resets the value to the default of 0.2.
    New: Values can be specified from 0% to 100%, or from 0 to 1. A value of 100% or 1 represents full opacity. Specifying 0 is invalid and does not change the opacity.

Library Security Updates

  • Upgraded OpenSSL to 3.6.4.
  • Upgraded Skia to m149.
  • Upgraded libtiff to 4.7.2.

Corrections:

The following issues have been corrected.

Conversion from Word (DOC)

  • Differences between the document creation environment and the OSDC execution environment, such as variations in the languages used, caused font names to differ. As a result, the system interpreted the fonts used in the document as having been replaced with different fonts during conversion, leading to differences in how line spacing was handled.
  • When there was a footnote on the previous page, a blank space appeared at the top of the next page.

Conversion from Excel

  • Fixed an issue where an error occurred when specifying "-xlspaper" with "graph: sheet:".
